\ To all whom'z't may concern:

Be it knownthat I, EDWARD CALUSINSKI,

a citizen of the UnitedStates, anda resident 'of the city of Chicago, inthe county of Cook and State of Illinois, have invented a new and usefulImprovement in Beds, of which the following is a full, clear, and exactdescription.

My 1nvent1on beds and it consists in the combinatlons, constructions,and arrangements herein described and claimed.

An object of my invention is to provide a bed that is constructed topermit positioning of the mattress supporting means embodied therein invarious positions In order that a sick person may be supported therebyto receive proper treatment and in order that the maximum of comfort maybe provided for the patient.

A further object of my inventionis' to provide a device of the typedescribed in which the means for adjusting the mattress 1 supportingmember to support a patient in various positions, as for instance insitting,

f semi-reclining, and recumbent positions, can

be operated without removing the patient from the bed.

thehead and foot portions.

Afurther object of my invention is to provide in a device of the typedescribed, a

. foldable table adapted'to be extended and maintained inoperativeposition close to the patient or to befolded and moved out of the waywhenin inoperative'position.

-A further object of my invention is to provide adevice of the typedescribed that is relatively simple in construction and 0peration, andnot likely to get out of order easily.

Other objects and advantageswill appear .in the following specification,and the novel Y features of the invention will be particularly pointedout in the appended-claims.

' My invention is illustrated in the accompajnying drawings, formingpart of this application, in which i 1 showing a mattress supportingmember embodied therein in tilted position and the relates toimprovements inmembers 2 and 4 are connected in the usual and abut oneanother so that when a'pluraL' table portion of the devicein extended oroperative position, I i Figure 2 is a view similar to Figure 1, showingtheimattress supporting member in another position and the table in itsfolded or inoperative position,

the line 4 20f Figure 6 is a plan View of thefragmentary portion ofthedevice shown in Figure In carrying out my 1nvention,.1' provide headposts 1l havmgsecured thereto in any suitable manner, an end bar orframe member2 and foot posts connected by an end frame member 4. The'endframe manner by theside bars or'frame members 5 and 6, so thatarigid'be'dstead frameis provided. 1 s r A mattress support comprisingparallel end bars 7 and 8 having'connected sections 9; l0, and 11 ofwire netting or the like interposed -therebetw'een"and connected theretoby springs-l2l2 is movablysupported at its ends substantially parallelwith the rigid frame, and in a-higher plane by means which will" behereinafter described in detail. It will be noted that the adjacent endsof the Sections 9 and 10 are hingedly connectedto one another at 13and'that a plurality of connectorlinks 14:, such as shown in'Figures 5and 6 are interposed between the adjacent 'ends 'of the sectionslO and11. Each ofthe links 14 is formed with a tongue 15 at one end thereofand with a'slot orsocket 16 in its opposite end. The tongue 15 of one ofthe connectors is arranged to enter the-socket 16 of'the adjacentconnector and is secured therein by a 'pin' '17, The contiguous walls ofthe tongue 15 and the slot 'l6ar'e straight ity'of'the connecting links14 are secured tolinks are permitted to move downwardly un der stressat'the point oftheir connection with one' anothe'r and are preventedfrom) moving upwardly out of a horizontal plane V at the same point onaccount of the engage Figure 1 is a side elevation of the device,

gether in the mannendescrib'ed, adjacent tors '14 are. each formed withdiametrically opposed lateral extensions l8-l8,each,having an opening 19therein adapted to receive the ends of wires composing the woven wirebody portions of the sections 10 and ll. The tongue 15 of one endconnector in the series provided is secured by one of the pins 17 in asocket 21 of an end plate 22 that has an integral depending lug 23. Achain 24 is connected at one end to the depending lug 28 and at itsother end to a lug or bracket 25 that is secured at 26 to the side bar5, as clearly shown in Figure 1. A tongue 27 of an end plate 28 issecured in the socket 16 of the other end connector in the series by oneof the pins 17. The end plate 28 is formed with a depending lug 29 and achain 30 that is similar to the chain 24: and is connected at 31 to thelug 29 and has its other end connected to the side rail 6.-

The end plates 22 and 28 are each provided with diametrically opposedopenings 32-32 adapted for connection, as by means of links 33-35 withthe adjacent portions of the mattress supporting sections 10 and 11.

To the. end that the mattress supporting frame may be supported normallyin a higher plane parallel with the rigid bedstead frame so that thesections thereof can be tiled in order to support a patient in variouspositions with a maximum degree of comfort, as for instance in sitting,reclining and recumbent positions, and that the sections 9 and 11 can betilted independently of one another, I provide a pair of parallelsupporting members 34-84 which are in effect bell crank levers; Theshorter arms, of the bellcrank levers are rigidly secured at 35 in anysuitable manner to the end frame member 7 adjacent and end thereof. Thebell crank levers 34-84; have their opposite ends rigidly secured zit-36to a transverse thrust bar 37 thathas a length equal to that of the endbar 7 and is disposed parallel therewith. The bell crank levers 3-34:are respectively fulcrumed within corresponding longitudinally extendingvertical :slots 38-38 in the side members 5 and 6, beng rotatablymounted on guide pins 39-39 that project respectively through horizontalslots 40-40 in the side bars 5 and'6 and have their inner ends fast inlateral extensions ll-a1 of a'transverse guide bar 42. The

.. guide bar i2 is fashioned intermediately to provide a depending boss43 provided with a threaded opening at adapted to receive a screw 45that constitutes a portion of a sleeve-46 rotatably mounted on a shaft47 andbeing journalled at 4E8adjacent its outer ,end n-theend bar 4.The'shaft 47 ext-ends the length of the rigid frame and has its otherend'jou rnalled at 49 in the end bar 2.

supporting the section 11 of the mat- Jtresssupporting member in themanner in- -dicatedfll provide a pair of relatively long arms. gfiQ- ;Wh.. r rigi ly s c re at able along the slots. Arms (A-5a are pivoted at-55 at their upper ends to the arms 50-50 and at 56-56 to the upper endsof rocker arms 57-57. 'The latter are intermediatel'y rigidly mounted at58-58 between pairs of upstanding lugs 59-59 integral with the sideframe members 5 and 6 on a transverse rock shaft 80 so that the rockerarms 57-57 can be moved about the shaft 80 through the slots 53-53. Therocker arms 57-57 are pivotally connected at 69-60 to corresponding endsof U-shaped linl-: s 61-61 which are respectively disposed within theslots 53-53 and formed with arms 62-62 extended and pivotally con nectedat 63-63 with links 64-64. The.

latter are entirely disposed within the slots 53-53 for slidablemovement by means of guiding and retaining pins 65-65 that are projectedthrough longitudinal slots 66-66 in the links ti l-64 and have theirends secured in the walls of the slots 53-53. The

links til-ea are pivotally connected at their other ends as at 67-67with connecting bars 68-68 which are in turn pivotally connected at69-69 with the members 50-50 at spaced distances from the lower endsthereof.

The bell crank levers 34.34 are likewise braced by connectors 7 0-70pivoted at their upper ends at 71-71 to the bell crank levers andpivoted at 72-72 between pairs of lugs that are formed integrally withlinks 74 lei having their lower end portions pivoted at 75-75 betweenthe walls of the slots The connectors 70-70 have their lower 7 endsabutting against shoulders or stop members 75-75' provided between thelugs 73 -73 integral with the ,connectors'74t-74 so that the movement ofthe same about their pivots 7 272 in one direction is .limited. 76-7 6are provided withtheir ends fast in the walls of the slots 38-38 so thatthe movement of the connectors 74-746 about their pivots 75-75downwardly is limited.

From the foregoing description of. the.

various parts of. the. device. the operation thereof may be readilyunderstood. The device is particularly suitable for use in hospitals andin caring vfor sick patients, since they can be supported in variouspositions in order that theproper treatment may be administered and inorderv to 'provide the maximiun of comfort. The positions of themattress supporting member may be changed without removing the patientfrom the beds Transversely extending stop pins- The shaft 47 is formedWith'a non-circular member 77 adapted to a spanner or socket wrench orthe like and rotation of the shaft 47 will occasion a like movement ofthe portion thereof adjacent to thehead end of the device that is formedto provide a worm 78. A gear 79 is rigidly mounted on a transverse rockshaft 80. The worm 78 is maintained in engagement with the gear 7 9 by aU shaped yoke or hanger '81 that is hung from the transverse shaft 80.Consequently, 0peration of the shaft 80 rocks the rocker arms 5T57 sothat the latter and the links 54-54 are moved into alinement tosupportthe section 11 in the position shown in Fig- 7 The links 6464 will alsobe moved ure 1. along the slots 53-53 and the bracing members .6868 willassume the positions illustrated in Figure l. The section 9 may now betilted by rotating the sleeve 46 which is formed with anon-circular endportion 82 adapted to a wrench or key. Itis obvious that rotatio'nof thesleeve 46 and-the integral screw will cause the guide bar 42 to be movedalong the slots 4040 and the section 9 willbe tilted to the positionshown and will'be supported in that position by the bell crank levers34'34 which are in turn braced by the connectors 70-7O and 74 74. Whenthe several'sections of themattress supporting members are in theposition shown in Figure 1, a patient may be supported in a sittingposition. I Then the several sections are in' the position shown inFigure 2, the device "is suitable for use as a bed.

embodied in the device.- Two article supporting members 84 and 85 arehingedly connected at 83 so that the member canbe folded together. Asupporting .arm 86Vis pivoted at 87 to a lugs 88 thatdepends from theunder surface of the table member 85 i In Figure 1,1 show aj foldingtable that is connector 90 is connected to the arm5i0 by a f i link 93that has one end pivoted to the arm 50 and its other end pivoted at 94to the L-shaped connector 90. It is thus obvious that the table can bemoved into position close to a patient who is supported in a recliningposition. :lVhen not in use, the table can be folded and moved out ofthe way as g shown in Figure 2.
